CSV写从标签列开始

Question

这可以很好地工作，但是问题是，当它写第一行时，它会与列标签相邻。其余的都很好。

我该如何解决？

row = []

with open('train.json') as json_data:
     d = json.load(json_data)

for each in d:
    sentence = each["text"]
    senti_value = each["sentiment"]

    row.append(sentence)
    row.append(senti_value)

    with open('data.csv', 'a') as csvFile:
        writer = csv.writer(csvFile)
        writer.writerow(row)

    csvFile.close()

    row = []

在右上角的这张图中，句子出现之后。我必须解决此问题并将其移至下一行。

您要一次写列标题，然后写数据行：

with open('train.json') as json_data:
     d = json.load(json_data)

column_headers = ['Sentence', 'Senti value']

# Open the csv file outside the loop, so we only open it once.
# We could open in 'w' mode, but 'a' is OK too.
with open('data.csv', 'a') as csvFile:
    writer = csv.writer(csvFile)

    # Write the column headers to the file.
    writer.writerow(column_headers)

    # Write each data row to the file.
    for each in d:
        sentence = each["text"]
        senti_value = each["sentiment"]
        row = []
        row.append(sentence)
        row.append(senti_value)

        writer.writerow(row)
